Taxonomy:

Citation: Mesozoic Heterococcoliths inc sedis
Taxonomic rank: informal group of families
Taxonomic discussion: In addition to these genera two predominantly Cenozoic heterococcoliths inc sed have been recorded from the Mesozoic - Ellipsolithus (one species described from the Turonian of Tanzania by Lees & Bown 2016) and Markalius (M. inversus is sporadically reoded from the Late Cretaceous)

Distinguishing features:
Parent taxon (Mesozoic nannofossils): Predominantly Mesozoic nannofossils - except for Braarudosphaerales
This taxon: Heterococcolith genera which do not show characteristic features of any of the well-established families.
